Abstract
An integrated dynamic memory includes a memory cell array having memory cells each assigned to one of a plurality of groups. The plurality of groups are divided into defect-free groups having exclusively defect-free memory cells and into defective groups having at least one defective memory cell. The memory further includes a memory configuration table that contains a list of the defect-free groups and an assignment unit that, based upon the entries in the memory configuration table, executes memory accesses only to those memory cells assigned to a defect-free group. The total capacity of the memory module, then, is not fixed once and for all with fabrication, but, rather, results only after a memory test, or may even vary in the course of the module lifetime.
